高精度磁法在冯庄地区找矿中的实际应用及启示

High Precision Magnetic Method in Feng Zhuang Area Prospecting in Practical Application and Enlightenment

河南省泌阳县冯庄地区的主要围岩蚀变常见黄铁矿化、褐铁矿化、硅化、绿泥石化、绿帘石化、绢云母化、高岭土化、碳酸盐化等。这是区内主要的找铁矿标志。通过对该地区进行的前期标本测试,对矿区主要岩性磁性差异进行了解,决定使用1:1万地面高精度磁力ΔT测量,圈定该区异常范围,从而为进一步地质找矿提供有用信息。

The Henan province Biyang County Feng Zhuang area of the main wall rock alteration common pyritization, limonitization, sihcification,chloritization, epidotization,sericitization, kaolin,carbonation.This area is mainly for iron mark.Based on the region of the prophase test,the mining area of the main lithology magnetic differences in understanding, decided to usel：lmillion ground high prcision magnetic survey in the area of AT,delineated the abnormal range,so as to provide useful information for further geological prospecting.
